The Science of Human Connection: Why We’re Wired to Share

Humans have always thrived together, from ancient campfires to modern coworking spaces. In fact, our brains are literally built to connect. Neuroscience shows that social rejection activates the same brain regions as physical pain, signaling that human connection and social bonds have become a necessity, not a luxury.

Even simple acts like sharing good news are hardwired: people are wired to share good news because the act fosters deeper connections. In other words, spreading happiness, sharing things, and helping others isn’t just nice; it makes us feel good and strengthens our networks.

Evolutionary Roots of Sharing and Human Connection

Early humans survived by hunting and gathering in groups, so sharing food and helping one another increased their chances of survival. Evolutionary scientists argue that we didn’t become cooperative because we were naturally altruistic; rather, altruism emerged to help cooperative groups succeed. In fact, researchers conclude that “we must cooperate to survive, and we are altruistic to others because we need them for our survival”. In a group context, people who share resources and burden outlast those who compete alone. Over time, evolution favored brains wired for teamwork and trust, thereby seeding our instinct to share, which remains with us even today.

Our Social Brains and Well-Being

We may think of ourselves as independent, but the brain tells a different story: our brains default to social mode. After any non-social task, studies find the brain reflexively “switches back” to social thinking, as if it were waiting to reconnect with others. This “social readiness” underlies our ability to work together. As psychologist Matthew Lieberman explains, we have a “profound proclivity” to infer what others are thinking or feeling- a skill that gives us “an unparalleled ability to cooperate and collaborate”. 

Not only that, but strong social ties directly affect our health. Studies of animals and humans show we are wired such that our well-being depends on connections with others. When friendships or communities break down, people often suffer from loneliness and exclusion truly hurt. This biological link explains why caring responses (or the lack of them) to any news can make or break relationships. We crave community, so every time we share a smile, a meal, or a kind word, we’re tapping into deep brain systems built for connection.

Everyday Acts of Sharing

These instincts play out in our daily lives. Simple shared experiences like meals, commutes, or brainstorming sessions forge real bonds and boost well-being.

Sharing a meal: Sitting down for a meal together does more than fill bellies. Oxford researchers found that people who eat socially report higher happiness and a stronger sense of community. In short, breaking bread together satisfies a deep social need.

Sharing a ride: Carpooling is another powerful example. Hopping into a car with a coworker or classmate turns a dull commute into a time to catch up. And it’s not just anecdotal: one summary notes that chatting in a carpool “can boost your mood, reduce feelings of loneliness, and strengthen your social bonds”. Indeed, the act of carpooling is said to be about more than splitting gas costs- it’s “about sharing health and well-being”. Sharing the ride means sharing conversation, support, and even stress relief.

Sharing ideas: Even exchanges of ideas or a simple handshake at work tap into this wiring. Every time colleagues swap tips over coffee or network at an airport lounge, they’re exercising their social brain. Neuroscience shows our thoughts reflexively drift to understanding others, and that talent primes us to collaborate effectively. In practice, that means brainstorming together or mentoring a peer often leads to better solutions for everyone. Each friendly discussion or referral strengthens trust and expands our network, furthering a cycle of mutual support.

POOLit: Sharing for Professionals

Putting these ideas into practice, POOLit is a new app that connects verified professionals for sharing and networking. Its goal is to make sharing rides, time, and help easy and trustworthy. For example:

• POOLit Carpool: Connect with professionals to share rides with others on similar routes, making your commute easier and more enjoyable. You save money and get company on the road.

  
  

• POOLit Connect: Meet and engage with verified professionals on the go, wherever you are, at any key locations like airports, cafés, or even coworking spaces. Turn idle waiting time into real networking opportunities. 

• POOLit Buddy: Request or offer secure help with local deliveries or travel assistance. Whether you need a trusted courier or a travel companion, you connect with qualified professionals to share the load.

Each POOLit feature is built on trust and collaboration. By keeping members as verified professionals, the app ensures that sharing (rides, conversations, or errands) happens authentically. In doing so, PO

Final Thoughts: Humans aren’t just social by choice 

Our brains and bodies depend on connection. Generosity, conversation, and cooperation are hardwired survival strategies. When we share resources or experiences (a meal, a commute, a chat), we activate those ancient networks that make us happier and healthier. Modern tools like POOLit simply make it easier to live out this fundamental truth. After all, as science shows, we’re all wired to share, and when we do, everyone wins.
